Tags are great enhancements to monitors. For those in the Orion world, they are similar to Custom Properties. At one time, we were working with a now defunct software developer to create a 'triage' troubleshooting system, whereby the system processes emails received from ipMonitor, checks the tags, and performs basic troubleshooting prior to opening up a trouble ticket for a human to look at. Through the use of tags, we attempted to pass information such as the router to SSH into, the interface to do 'show int' on, and the IP to ping. The system was supposed to perform these very basic components of first-line-of-defense troubleshooting and open a ticket so techs didn't have to do it all themselves.
Unfortunately, the software developer never delivered what they promised. :-( Maybe someone else out there will see this and develop something similar to share with the community.
